Fix Recommendation

Configure the PAWs to use IPsec, SSH, TLS, or TLS/HTTPS for all connections between the PAW and managed IT resources on the intranet.

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing" to "Enabled".

Check Contents

On the PAW workstation, verify IPsec, SSH, TLS, or TLS/HTTPS is configured for all connections between the PAW and managed IT resources on the intranet.

Verify the following registry setting:
Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SYSTEM\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\

Value Name: Enabled

Value Type: REG_DWORD
Value: 1

Warning: Clients with this setting enabled will not be able to communicate via digitally encrypted or signed protocols with servers that do not support these algorithms. Both the browser and web server must be configured to use TLS; otherwise, the browser will not be able to connect to a secure site.

If on the PAW workstation the registry value for HKEY_LOCAL_MACHINE does not exist or is not configured as specified, this is a finding.
